1 A Practical Guide to Free Energy Devices Device Patent No 33: Last updated: 22nd May 2008 Source: Patrick Kelly This patent gives details of a permanent magnet motor which uses electromagnet shielding to achieve ontinuous rotation. The input power is very small with even a 9-volt battery being able to operate the motor. The output power is substantial and operation up to 20,000 rpm is possible. Construction is also very simple and well within the capabilities of the average handyman. It should be realised that the power of this motor comes from the permanent magnets and not from the small battery input used to prevent lock-up of the magnetic fields. US Patent 5,455,474 3rd October 1995 Inventor: Charles Flynn Magnetic motor construction ABSTRACT The present invention is a motor with permanent magnets positioned so that there is magnetic interaction between them. A coil placed in the space between the permanent magnets is used to control the magnetic interaction. This coil is connected to a source of electric potential and controlled switching so that closing the switch places a voltage across the coil and affects the magnetic interaction between the permanent magnets as to produce rotational movement of the output shaft.

2 BACKGROUND OF THE INVENTION The present invention is an improvement over the inventions disclosed in patent applications 07/322,121 and 07/828,703. The devices disclosed in those applications relate to means to produce useful energy using permanent magnets as the driving source. This is also true of the present invention which represents an important improvement over the known constructions and one which is simpler to construct, can be made to be self starting, is easier to adjust, and is less likely to get out of adjustment. The present construction is also relatively easy to control, is relatively stable and produces an amazing amount of output energy considering the source of driving energy that is used. The present construction makes use of permanent magnets as the source of driving energy but shows a novel means of controlling the magnetic interaction between the magnet members in a manner which is relatively rugged, produces a substantial amount of output energy and torque, and in a device capable of being used to generate substantial amounts of energy that is useful for many different purposes. The present invention resides has a fixed support structure with one or more fixed permanent magnets such as an annular permanent magnet mounted on it with the pole faces of the permanent magnet on opposite faces of the magnet. The device has one or more relatively flat coils positioned around the edge of one of the faces of the magnet, and a shaft extends through the permanent magnet with one or more other permanent magnets attached to it. The spaced permanent magnets and the fixed permanent magnet have their polarities arranged to produce a magnetic interaction between them. The device also includes a circuit for selectively and sequentially energising the coils to control the magnetic interaction between the magnets in such a manner as to produce rotation between them. Various methods can be used to control the application of energy to the coils including a timer or a control mechanism mounted on the rotating shaft. This design can be made to be self-starting or to be started with some initial help to establish rotation. OBJECTS OF THE INVENTION It is a principal object of the present invention to teach the construction and operation of a relatively simple, motor-like device using permanent magnets in an unique manner to generate rotational or other forms of movement. Another object is to teach the construction and operation of a relatively simple, motor-like device having novel means for coupling and/or decoupling relatively moveable permanent magnets to produce motion. Another object is to provide novel means for controlling the coupling and decoupling of relatively moveable permanent magnets. Another object is to make the generation of rotational energy less expensive and more reliable. Another object is to teach a novel way of generating energy by varying magnetic interaction forces between permanent magnets. Another object is to provide an inexpensive way of producing energy. Another object is to provide a substitute source of energy for use in places where conventional motors, generators and engines are used. These and other objects and advantages of the present invention will become apparent after considering the following detailed specification of preferred embodiments in conjunction with the accompanying drawings. 2/26

11 DETAILED DESCRIPTION In the drawings, the number 10 refers to a device constructed according to the present invention. The device 10 includes a stationary base structure including an upper plate 12, a lower plate 14, and spaced posts connected between them. Mounted on the upper plate 12 is a fixed permanent magnet 24 shown annular in shape which has its North pole adjacent to the upper surface of plate 12 and its South pole facing away from plate 12. Referring to Fig.2, the permanent magnet 24 is shown having seven coils mounted flat on its upper surface. Seven coils are shown, and the coils have electrical connections made through plate 12 to other circuit members which will be described later in connection with Fig.13. Another member 40 is mounted on the upper surface of the lower plate 14 and a similar member 42 is mounted on the underside of the plate 12. A shaft 44, (shown oriented vertically for convenience) extends through aligned holes in the members 42, 12 and 24. The lower end of shaft 44 is connected to disk 46 which has a pair of curved openings 48 and 50 shown diametrically opposite to each other, a little in from the edge of disc 46. The purpose of these openings 48 and 50 will be explained later on. Shaft 44 is also connected to another disc 52 which is located on the shaft so as to be positioned adjacent to the coils Disc 52 has a pair of permanent magnets 54 and 56 mounted on or in it positioned diametrically opposite to each other. Magnets 54 and 56 have their north and south poles oriented as shown in Fig.2, that is with north poles shown on their lower sides and their south poles on the upper sides. This is done so that there will be mutual magnetic attraction and coupling between the magnets 54 and 56 and the fixed magnet 24. The polarity of the magnets 54 and 56 and/or of the magnet 24 can also be reversed if desired for some purposes to produce relative magnetic repulsion between them. Referring again to Fig.2, the lower plate 40 is shown having a series of phototransistors mounted on its upper surface and spaced out as shown. These phototransistors are positioned under the centres of the coils which are mounted on magnet 24. An equal number of infra red emitters are mounted on the under 11/26

12 surface of the member 42 aligned with the phototransistors. There are seven infra red emitters shown, each of which is in alignment with a respective one of the seven phototransistors and with one of the seven coils This arrangement is such that when the shaft 44 and the components attached to it, including discs 46 and 52, rotate relative to the other members including magnet 24, the curved openings 48 and 50 pass under the infra red emitters and cause the phototransistors to switch on for a predetermined time interval. This establishes a sequence of energised circuits which powers coils 26-38, one at a time, which in turn, causes a momentary interruption of the magnetic interaction between one of the permanent magnets 54 and 56 and magnet 24. When a coil is mounted on top of a permanent magnet such as permanent magnet 24 and energised it acts to concentrate the flux in a symmetrical magnetic field resulting in a non-symmetrical field when another permanent magnet is above the coil on magnet 24. This results in uneven or non-uniform forces being produced when the coil is energised and this causes a torque between the two permanent magnets, which tries to move one of the permanent magnets relative to the other. Fig.3 shows the position when one of the magnets 54 is located immediately above one of the coils, say, coil 26. In this position there would be magnetic coupling between the magnets 54 and 24 so long as there is no voltage across the coil 26. However, if a voltage is placed across the coil 26 it will interrupt the magnetic coupling between the magnets 54 and 24 where the coil is located. This means that if there is any torque developed, it will be developed to either side of the coil 26. Without energising the coil 26 there will be full attraction between the magnets 24 and 54 and no rotational force will be produced. Referring to Fig.4 there is shown the relative positions of the movable magnets 54 and 56 for one position of disc 52. For example, the magnet 54 is shown located immediately above the coil 26 while the magnet 56 is shown straddling portions of the coils 32 and 34. If, in this position, coil 32 is energised but coils 34 and 26 are not energised, then the magnetic coupling between magnet 56 and magnet 24 will be oriented at an angle shown illustrated by the arrow in Fig.4, and this attractive coupling will tend to move disc 52 to the right. Since coil 26 is not powered up, there is full coupling between magnet 54 and magnet 24 but this has no effect since it does not have a directional force. At the same time, coil 38 which is the next coil over which the magnet 54 will move, is also not powered up and so it will have no rotational effect on disc /26

13 As disc 52 continues to rotate, different coils in the group will be energised in sequence to continue to produce a rotational magnetic coupling force between disc 52 and magnet 24. It should be noted, however, that all of the rotational force is produced by interaction between the permanent magnets and none of the rotational force is produced by the coils or by any other means. The coils are merely energised in sequence to control where the magnetic interaction occurs, and this is done in a manner to cause disc 52 to rotate. It should also be understood that one, two, or more than two, permanent magnets such as the permanent magnets 54 and 56 can be mounted on the rotating disc 52, and the shape and size of the rotating disc 52 can be adjusted accordingly to accommodate the number of permanent magnets mounted in it. Also, disc 52 can be constructed of a non-magnetic material, the only requirement being that sufficient structure be provided to support the permanent magnets during rotation. This means that disc 52 need not necessarily be constructed to be round as shown in the drawing. Fig.5 and Fig.6 are similar to Fig.3 and Fig.4 but show a construction where the permanent magnets 54 and 56 are turned over so that instead of having their north poles facing magnet 24 they have their south poles facing magnet 24 but on the opposite side of the coils such as coils The construction and operation of the modified device illustrated by Fig.5 and Fig.6 is similar to that described above except that instead of producing magnetic attraction forces between the magnets 54 and 56 and the magnet 24, magnetic repulsion forces are produced, and these repulsion forces can likewise be used in a similar manner to produce rotation of the member 52, whatever its construction. Fig.7 shows a modified embodiment which includes all of the elements shown in Fig.1 and Fig.2 but in addition has a second stationary permanent magnet 102 which is mounted above rotating disc 52 and has its coil members such as coil members 26A-38A mounted on its underside. Magnet 102 operates with the magnets 54 and 56 similarly to the magnet 24 and can operate in precisely the same manner, that is by producing attraction force between the magnet members or by producing repulsion forces between them, each being used to produce relative rotational movement between the rotor and the stator. It is also contemplated to make the construction shown in Fig.7 so as to produce attraction forces between the magnets 54 and 56 on one side thereof and cooperating repulsion forces which add to the rotation generating forces produced on the opposite side. 13/26

14 Fig.8 and Fig.9 are similar to Fig.3 and Fig.4 but show the relationship between the magnets 54 and 56 and the members 24 and 102 located on opposite sides. These figures show one form of interaction between the rotating magnets 54 and 56 and the stationary magnets 24 and 102 located as shown in Fig.7. In this construction, the device produces attractive rotating force only. Fig.10 and Fig.11 are similar to Fig.8 and Fig.9 except that in these figures both attraction and repulsion forces are shown being produced in association with the stationary magnets on opposite sides of the rotating magnets. Note also that the coils being energised on opposite sides of disc 52 are energised in a different arrangement. 14/26

15 Fig.12 is a side view similar to Fig.7 but showing the way in which several stationary and rotating magnetic members such as the discs 24 and 102 can be mounted on the same shaft, in almost any number of repeating groups to increase the amount of torque produced by the device. In Fig.12, the same power source and the same circuit arrangement can be used to energise the phototransistors and the infra red emitters. However, depending upon whether attraction or repulsion forces are used to produce the rotation or some combination of them, will depend upon the order in which the coils associated with the stationary magnetic members are energised. Fig.13 is a circuit diagram for the device shown in Fig.1 and Fig.2, showing the circuit connections for the coils and for the circuit elements associated with them. A similar circuit can be used for the construction shown in Fig.7 and Fig.12. The circuit also includes connections to the various phototransistors and infra red emitters. In Fig.13, the circuit 120 is shown including a power supply 122 which may be a battery power supply, a rectified AC power supply or an AC or pulsed power supply. The positive side 124 of the power supply 122 is shown connected to one side of each of the coils 26-38, coil 26 and the circuits associated with it 15/26

16 being shown in bold outline and including connections to one side of a resistor 128 and to one side of the photo transistors The opposite side of the coil 26 is connected to one terminal of MOSFET 126. The opposite side of the resistor 128 is connected to one side of the infra red emitter 72, as well as to the corresponding sides of all of the other infra red emitters The opposite sides of the infra red emitters are connected by lead 130 to the negative terminal side 132 of the power supply 122. With the circuit as shown, the infra red emitters are all continuously energised and produce light which can be detected by the respective phototransistors when one of the openings 48 or 50 passes between them. When this happens, the respective phototransistor 58 will conduct and in so doing will apply positive voltage on the associated MOSFET 126, turning the MOSFET on, and causing the voltage of the source 122 to also be applied across the coil 26. The circuit for this is from the source 122 through the coil 26, through the MOSFET 126 to and through the lead 134 to the opposite side of the source 122. When the supply voltage is applied across the coil 26, it operates to limit or prevent magnetic communication between whichever one of the magnets 54 or 56 happens to be positioned adjacent to the coil 26 which is in the space between that magnet 54 or 56 and the magnet 24. This circuit is shown in bold in Fig.13. By properly timing and controlling the application of voltage to the various coils in the manner described, the magnetic coupling between the magnets 54 and 56 and the magnet 24 can be accurately controlled and cause angular magnetic attraction between the magnet 54 (or 56) and magnet 24, which angular attraction (or repulsion) is in a direction to cause rotation of the rotating parts of the structure shown in Figs. 1, 2, 7 and 12. It should be understood that each of the coils will be controlled in the same manner, that is, will have a voltage appearing across it at the proper time to control the direction of the magnetic coupling in a manner to produce rotation. The rotating portions will continue to rotate and the speed of rotation can be maintained at any desired speed. Various means can be used to control the speed of rotation such as by controlling the timing of the DC or other voltage applied to the various coils, such as by using an alternating or pulsed current source instead of a direct current source or by loading the device to limit its rotational speed. It is especially important to note that the energy required to operate the subject device is minimal since very little electrical energy is drawn when voltage is applied across the various coils when they are energised. A well known equation used for conventional motor art, is: Hence, Power (in watts) = Speed x Torque / 9.55 W = S x T / 9.55 This equation has limited application to the present device because in the present device the torque is believed to be constant while the speed is the variable. The same equation can be rewritten: T = 9.55 x W / S or S = 9.55 X W / T These equations, if applicable, mean that as the speed increases, the watts divided by the torque must also increase but by a factor of Thus if torque is constant or nearly constant, as speed increases, the power output must increase and at a very rapid rate. It should be understood that the present device can be made to have any number of stationary and rotating magnets arranged in stacked relationship to increase the power output, (see Fig.12) and it is also possible to use any desired number of coils mounted on the various stationary magnets. In the constructions shown in Figs. 1, 7, and 12 seven coils are shown mounted on each of the stationary magnets but more or fewer coils could be used on each of stationary magnet depending upon the power and other requirements of the device. If the number of coils is changed the number of light sources and photo-detectors or transistors will change accordingly. It is also important to note that the timing of the turning on of the various phototransistors is important. The timing should be such as that illustrated in Fig.4, for example, when one of the coils such as coil 32 is energised to prevent coupling in one direction between magnet 56 and magnet 24, the adjacent coil 34 will not be energised. The reasons for this have already been explained. 16/26

17 Fig.14, shows another embodiment 140 of this motor. This includes a stationary permanent magnet 142 which has a flat upper surface 144 and a lower surface 146 that is circumferentially helical so that the member 142 varies in thickness from a location of maximum thickness at 148 to a location of minimum thickness at 150. The thickness of the member 142 is shown varying uniformly. Near the location of the thickest portion 148 of the permanent magnet 142 and adjacent to the surface 144 is an air coil 152 shown formed by a plurality of windings. A shaft member 154 is journaled by the bearing 156 to allow rotation relative to the stationary permanent magnet 142 and is connected to a rotating disc 158. The disc includes four spaced permanent magnets 160, 162, 164 and 166 mounted on or in it. The permanent magnets are positioned to rotate close to the stationary permanent magnet 142 but with the coil 152 positioned between them. Coil 152 is connected into a circuit similar to that shown in Fig.13 and so the circuit will not be described again. The principals of operation of the device 140 shown in Fig.14 are similar to those described above in connection with Fig.1 and other figures. It is important to note, however, that the permanent magnets rotate relative to the permanent magnet 142 because of the increasing coupling between them and the permanent magnet due to the increasing peripheral thickness of the permanent magnet. Thus the member 158 will rotate in a counter-clockwise direction as shown, and each time one of the magnets moves into a position adjacent to the thickest portion 148 of the fixed permanent magnet 142 the coil 152 will have voltage applied across it, otherwise there would be a tendency for the member 158 to stop or reduce the rotational force. In order to overcome this the coil 152 is energised each time one of the permanent magnets is in the position shown. The rotating disc 158 is connected through the shaft 154 to rotating disc 168 which has four openings 170, 172, 174 and 176 corresponding to the locations of the permanent magnets so that each time one of the permanent magnets moves to a position adjacent to the thickest portion 148 of the stationary permanent magnet 142 the coil 152 will be energised and this will reduce or eliminate the coupling between the rotating and stationary magnets that would otherwise slow the rotating portions down. The circuit connected to the coil 152 includes the same basic elements described above in connection with Fig.13 including varying a photocell 178, an infra red emitter 180 and a MOSFET 182 connected into a circuit such as that shown in Fig.13. The timing of the energising of the coil 152 is important and should be such that the coil will be energised as the respective permanent magnets move to a position in alignment or substantial alignment with the thickened portion 148 of the stationary permanent magnet /26

18 Fig.15 shows a basic simplified form 190 of the present device which includes a rotary member 52A having a single permanent magnet portion 54A mounted on it. The device also has a stationary permanent magnet 24A with a single air coil 26A positioned in the space between the members 52A and 24A in the manner already described. The construction 190 is not self-starting as are the preferred embodiments such as embodiment 10 but the rotary portions will rotate continuously once the device is started as by manually rotating the rotary portions. The construction 190 will have other portions as described above but the output from the construction will be less than the output produced by the other constructions. Fig.16 shows another simplified version 200 of the device wherein the member 52B is similar to the corresponding rotating member 52A shown in Fig.15. However, the fixed structure including the permanent magnet 24B has three windings 26B, 28B and 30B located at spaced intervals adjacent to the upper surface of it. The construction shown in Fig.16 will produce more output than the construction shown in Fig.15 but less than that of the other constructions such as that shown in Figs. 1, 2, 7 and 12. Obviously, many other variations of the constructions shown in the application are also possible including constructions having more or fewer coils, more or fewer rotating magnetic portions, more or fewer rotating members such as disc 52 and more or fewer stationary members such as magnets 24 and 142. Figs illustrate some of the underline principles of the present invention. Fig.17 shows an air coil 210, positioned in space, with an electric potential applied across it. With the energising voltage applied, the electro-magnetic field of air coil 210 extends substantially equally in the space above and below the coil as shown in dotted outlined. 18/26

19 Fig.18 shows the air coil 210 positioned adjacent to one side (the north side) of permanent magnet 212. In Fig.18 no voltage is applied across the air coil 210 and therefore the coil does not produce an electro-magnetic field as in Fig.17. Under these circumstances, the air coil 210 has no effect on the magnetic field of the permanent magnet 212 and the field of the permanent magnet is substantially as shown by the dotted outlines in Fig.18. Fig.19 is similar to Fig.18 except that in Fig.19 the air coil 210 has an electric potential applied across it and therefore has an established electro-magnetic field shown again by dotted outline. The electro-magnetic field of the air coil 210 modifies the magnetic field of the permanent magnet 212 in the manner shown. If coil 210 is placed in contact with, or close to the surface of, the permanent magnet and it is energised so that its polarity is opposite to that of the permanent magnet then the field produced is similar to that shown in Fig.19. Note that the field of coil 210 and the field of the permanent magnet 212 directly beneath the air coil 210 are in opposition and therefore act to cancel one another. Coil 210 would be defined to produce a counter-magnetomotive force which acts to cancel the field of the permanent magnet 212 in the region where the air coil 210 exists and the amount of the field in that region of the permanent magnet 212 that is cancelled is the remainder of the difference in magnetomotive force between the region of the permanent magnet 212 and the counter magnetomotive force of the air coil 210. Note that, since the field of permanent magnet 212 is only altered in the region of the air coil 210, the geometric magnetic field characteristics of the permanent magnet 212 can be altered selectively based upon the size of the coil 210, the number of air coils 210 and the amount of counter magnetomotive force being produced by the air coil /26

20 Fig.20 is similar to Fig.19 except that a second permanent magnet 214 is positioned at a location spaced above the air coil 210. In Fig.20 no voltage is applied across the air coil 210 and therefore the air coil 210 does not have an electro-magnetic field. Thus Fig.20 shows only the combined affect of the fields of the permanent magnets 212 and 214. Since the permanent magnets 212 and 214 are positioned so that their respective north and south poles are close together, there will be a strong attractive force between them at the location of the air coil 210. Fig.21 is a view similar Fig.20 but with an electric potential applied across the air coil 210 and with the upper permanent magnet 214 displaced to the left relative to its position in Fig.20. Note that in Fig.21 the shape of the electro-magnetic field of the air coil 210 is concentrated and shifted somewhat to the right and upward. This shift of the electro-magnetic field concentrates the magnetic coupling between the magnets 212 and 214 to the left thereby increasing the tendency of the upper permanent magnet 214 to move to the left. A much smaller magnetic coupling occurs between the right end of the permanent magnets 212 and 214 and thus the force tending to move the permanent magnet 214 to the right is much less than the force tending to move it to the left. This is illustrated by the size of the arrows shown in Fig /26

21 Figs show four different positions of the upper permanent magnet 214 relative to the lower permanent magnet 212. In Fig.22 because of the position of the upper permanent magnet 214 relative to the air coil 210 there is a concentration of the magnetic coupling force tending to move the upper permanent magnet 214 to the left. This force increases in Fig.23 and Fig.24 until the upper permanent magnet 214 reaches the position shown in Fig.25 where all of the magnetic coupling is directed substantially vertically between the permanent magnets 212 and 214 and in this position there is little or no torque as a result of coupling energy between the permanent magnets 212 and 214 tending to move them relative to one another. The principles illustrated in Figs are at the heart of the present invention and explain where the 21/26

22 energy comes from to produce relative movement between the permanent magnets. The present device has application for very many different purposes and applications including almost any purpose where a motor or engine drive is required and where the amount of energy available and/or required to produce the driving force may vary little to nil. Applicant has produced devices of the type described herein capable of rotating at very high speed in the order of magnitude of 20,000 RPMs and with substantial torque. Other lesser speeds can also be produced, and the subject device can be made to be self starting as is true of the constructions shown in Figs. 1, 2, 7 and 12. Because of the low power required to operate the device applicant has been able to operate same using a commercially available battery such as a nine volt battery. CLAIMS 1.
